O/S

Information on this block such as the block tag, DD

revision, and execution time
The revision level of the static data of the DI block. The

value of this parameter is incremented each time a static

parameter value is changed.

The user description of the intended application of the

block
Used by an upper-level system to identify grouping of the

block. Not checked or processed by the block.
The identification number of the plant unit. This

information may be used in the host for sorting alarms.

The actual, target, permitted, and normal modes of the

block

Indicates the error statuses related to the block itself.
The primary discrete value (or process value) for

execution of the block’s functions.

Indicates the value and status of block’s output.

Allows use of values manually set instead of the limit

switch input from the transducer block. When Disable is

set for this value, the block reflects the actual input value

and status. 1 = Disabled, 2 = Active
Not used in a AV550G.
Not used in a AV550G.

Option to control access from the host computer and local

control panel to tuning and alarm parameters. Before

write access to a parameter, set the GRANT bit in this

parameter to have the operation right to be granted. Then

after write access, check the DENY bit in this parameter.

If the write access is complete successfully, it is not ON.
Sets the block input/output options.
Defines block actions depending on block status

conditions. For DI blocks of a AV550G, only bit 0 (Invert:

on/off state inversion) is effective.

The channel number of the transducer block’s logical

hardware channel connected to this block. This parameter

is always fixed for the DI block of the AV550G.

Sets the time constant of damping for PV_D.

The status of the limit switch signal transferred from the

transducer block
Shows the contents of an update event (a change to the

setpoint) upon occurrence.

Shows the contents of a block alarm upon occurrence.

Indicates the current alarm statuses.

Selects whether alarms associated with the block will be

automatically acknowledged.
Sets the alarm priority level.
Indicates the status of the input for the discrete alarm.
Indicates the status related to the discrete alarm.
